The penile circulation was assessed in 20 males submitted to aorto-iliac reconstructive surgery by preoperative angiography and Doppler measurement of penile acceleration ratio (PAR) and penile blood pressure pre- and postoperatively. Ten patients had erectile dysfunction preoperatively. Four of them regained erections after operation and a 5th patient got values indicating the same. One patient lost his erectile capacity due to resection of a wide collateral whereas another had his erections impaired but not lost by the operation. As a diagnostic tool the PAR method was better than the systolic penile blood pressure which was prone to under-diagnosis. We recommend the registration of both in patients with erectile dysfunction or occlusive arterial disease.
通过术前血管造影以及术前、术后阴茎加速度比（PAR）和阴茎血压的多普勒测量，对20例行主-髂动脉重建手术的男性患者的阴茎循环进行了评估。10例患者术前存在勃起功能障碍。其中4例术后恢复勃起，第5例患者的数据显示情况相同。1例患者因广泛侧支血管切除而丧失勃起能力，另1例患者勃起功能受损但未因手术而丧失。作为一种诊断工具，PAR方法比收缩期阴茎血压更好，后者容易漏诊。我们建议对勃起功能障碍或闭塞性动脉疾病患者同时记录两者。
